The long-serving prime minister, a champion of ‘illiberal democracy,’ has been politically isolated in much of Europe. But he has found common ground with the former and soon-to-be new U.S. president.

The European Union needs to rethink its support for Ukraine following Donald Trump's U.S. election victory, Hungarian Prime Minister Viktor Orban said before a summit of EU leaders on Friday, adding that Europe cannot finance the war alone.

Orban, who has grown increasingly isolated within the EU for his ties with Russia and opposition to military aid for Ukraine, has praised Trump as a "man of peace" who would quickly end the war. The two spoke by phone late on Wednesday, and Orban posted on social media: "We have big plans for the future".
